Decision evidence

What the documents establish

Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.

Usable capacity

95% of this battery’s nominal capacity is usable, 4.56 kWh in the scored configuration.

4.56 kWh usableScored configuration: US5000-B. Published range 4.56–72.96 kWh.

The remaining 5% stays in the pack as reserve; the home never draws it.

Nominal capacity is not stated here. The usable kWh and the depth-of-discharge percentage are sourced separately, at times from different documents and different module counts, so dividing one by the other would produce a nominal figure no manufacturer published.

No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.
